Abstract
A patient with end-stage renal failure, due to IgA nephropathy, was found to have a mediastinal mass. Biopsy specimen of the mass showed a necrotizing vasculitis. Antineutrophil antibodies to myeloperoxidase were strongly positive. To our knowledge, no case of a mediastinal mass due vasculitis has been reported in the literature, and our observation should lead to broadening of the spectrum of clinical manifestations of vasculitis.
